It depends on how many cases are pending at PEB when your ratings arrive at PEB. Mine took a month from the date that was reported on my MEB dashboard. I have also seen some people receive their findings less than two weeks after VA ratings. At this stage, I will tell you that patience is the key when your stuff is at PEB.

You should get your orders in like a week or two weeks at most then, you can move your date to the left depending if you want to take leave or sell your leave dates. It took 2 weeks for my orders from the date I signed my findings. Good luck!
